Description

[Detailed Description of the Invention] This invention relates to a slitting device that can easily remove hair debris adhering to the sliding surface of a fixed blade and a movable blade.

For example, in an electric shaver, a special brush is used to remove hair particles adhering to the sliding surface between the fixed blade and the movable blade of the shaving mechanism.

However, when the electric shaver is driven, that is, when the movable blades are reciprocating, when the brush is applied to the comb blades of the fixed and movable blades, the tips of the bristles are cut. Brushing cleaning has to be postponed, making it inconvenient to use.

Therefore, in this invention, a protrusion is formed on the lower surface of the movable member disposed on the upper surface side of the fixed blade, and the protrusion is fitted into the groove of the comb blade portion of the fixed blade, and the lower surface of the protrusion in this fitted state is connected to the fixed blade. By setting the movable blade flush with the sliding surface of the movable blade, hair debris can be removed by brushing regardless of the driving state.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing an example in which the shaving device according to the invention is applied to an electric shaver, in which 1 is the case body, 2 and 3 are for scouring, and the head 4 of the case body 1 is shown.
A fixed blade and a movable blade are arranged on the front side of the blade and have comb blade parts 5 and 6, respectively.

The fixed blade 2 has a pedestal protrusion 7 formed on the case body 1.
7 with a screw body 8 or fusion, etc., and the movable blade 3
receives the spring force of the compression spring 9 arranged below it,
It is pressed against the lower surface of the fixed blade 2 and is connected to a driver (not shown) so that it can reciprocate in the left-right direction (in the direction of arrows a and b).

Guide pins 10 and 10 project from the case body 1, and are fitted into elongated holes 11 and 11 formed in the movable blade 3, respectively.

Reference numeral 12 denotes a movable member disposed on the upper surface side of the fixed blade 2 so as to be movable in the front-rear direction (directions of arrows c and d).
Each groove 13 of the comb blade portion 5 of the fixed blade 2 is provided on the lower surface of the front end.
A large number of protrusions 14 are integrally formed, each of which is fitted into each of the protrusions 14 .

The lower surface 14a of the protrusion 14 is formed on the sliding surface S of the fixed blade 2 and the movable blade 3 (Figs.
(Figure).

Reference numeral 15 designates pins protruding from both left and right side surfaces of the movable member 12, and by fitting these pins 15 into guide grooves 16 formed on the inner surface of the side wall of the case body 1,
The movement of the movable member 12 back and forth is guided.

Of course, the movable member 12 does not have to be guided by the case body 1, but may be guided by the fixed blade 2.

Furthermore, it may be configured to be rotatable relative to the fixed blade 2.

Reference numeral 17 denotes a decorative bracket that is tested against the case body 1 by means of a screw body 18 or the like.

In the above configuration, if the movable member 12 is set at the position shown in FIG. The hair is sheared.

Here, if it is desired to remove hair debris adhering to the sliding surface S of the fixed blade 2 and the movable blade 3, the movable member 12 may be moved forward from the position shown in FIG.

In other words, due to the forward displacement of the movable member 12, this movable member 1
As shown in FIG. 4, the protrusions 14 formed on the fixed blade 2 fit into each groove 13 of the comb blade part 5 of the fixed blade 2, and the lower surface 14 a
is flush with the sliding surface S, so if you apply a brush (not shown) to the comb blade part 6 of the movable blade 3 and brush it, even during the reciprocating movement of the movable blade 3, Hair waste can be easily wiped off without cutting the bristles of the brush.

In particular, since the lower surface 14a of the protrusion 14 is flush with the sliding surface S, the blade surface of the movable blade 3 slides on the lower surface of the protrusion 14 as shown in FIG. It has the advantage that polishing is also done.

In order to enhance this polishing effect, carbon fine particles or the like may be included in the projections 14.

In the above embodiments, an electric shaver is used as an example, but the same effect can be achieved with other sharpening devices such as electric hair clippers.

Further, in the above embodiment, each groove 13 of the comb blade portion 5 of the fixed blade 2 is
Although the protrusions 14 of the movable member 12 are fitted into the respective grooves 13, the degree of fitting, that is, the width of the protrusions 14, should be such that the protrusions 14 have the effect of preventing the brush from entering. For example, in FIG. 5, it is sufficient if the difference between the width T1 of each groove 13 and the width T2 of the protrusion 14 is smaller than the cross-sectional diameter of the winter bristles of the brush.

As described above, this invention has a simple structure that only requires a movable body with protrusions that fit into each groove of the comb blade part of the fixed blade, and the brushing removal of hair can be performed regardless of the reciprocating movement of the movable blade. It is possible to provide a convenient cutting device that can be easily used.
